To rid your home of fleas, spread a box of Mule Team Borax (available in your store’s laundry soap isle), over your carpet. Use a broom and sweep it into the carpet. Wait a couple of hours then vacuum. The residual borax that remains in the carpet will kill the fleas and their larvae simply by drying them out.
Make sure your pets do not walk on the floor while the Borax is there. It can be absorbed into their feet.
Wishing you a flea-free summer from all of us at
